time a portion is desired. Such scoops are unsightly and unsanitary, collecting considerableidust and also causing much wastage of the ice cream. There is also further wastage occasioned by the fact that the ice cream container must be opened each time the scoop is entered, thus allowing the cold to be dissipated and requiring a greater amount of freezing or ice, in order to maintain the cream at the proper consistency. Y

It is therefore one of the objects of this invention to avoid thc difficulties heretofore enumerated by providing an apparatus which is sanitary and economical in operation, requiring less expenditure of energy to produce and retain the cold necessary to maintain the ice cream at the required temperature.

A further feature resides in the provision of a compact, neat appearing apparatus.

Another object is to produce a machine not easily liable to disarrangement and which can be manufactured at a moderate expense.

These and other like objects are accomplished by the novel construction and combination of parts as hereinafter described and shown in the accompanying drawings, and in which Fig. 1, is a vertical sectional view taken through an apparatus made in accordance with the invention, the device being in its normal position ready for operation.

Fig. 2, is a. top plan view of the same, parts being broken away to show the construction.

Fig. 3,is a view similar to Fig. 1, but showing the parts indelivery position.

Fig. 4, is a sectionalview taken on line 4-4 of Fig. 1. v

Fig. 5, is a fragmentary sectional view showing' a modified, coin actuated drive.

Flg. 6, 1s a sectional view taken on line 55 6-6 of Fig. 5.

Fig. 7, isla similar sectional view taken on line 7-7 of Fig. 5.

The device consists of a cylindrical tank 10 resting on a hollow base 11 to which it is 60 .frml secured by bolts passing through mating anges 12 and 13 on the tank and base respectively.

Entering the side of the base 11 is a tube 14'leading from a source of compresed air G5 and provided with a combined inlet and relief valve (not shown), thevuptured end ofthe tube projecting, through the center of the closed top of the basell to impinge upon the under side of a iston 15 movable in the 70 tank 10 and provi ed with packings in its periphery to prevent the leakage of air into the upper portion of the tank which is adapted to contain the substance to be dispensed.

The tank is provided with a: cover 16 having 75 a. downwardly extending peripheral flange 17 -and is secured to the upper end of the cylinder by wing bolts 18 in a manner to permlt ready removal; bolted on the cover 16 is a casing 19, generally an elongated parallel housing provided with bearings 20 and 21 at its respective ends in Vwhich is mounted a shaft 22 actuated by a hand wheel 23.

A cam 24 is figred on the shaft 22' and engaged in the groove of the cam is a stud 25 85 set in a slider 26 movable on the cover 16 and guided by the base of the casing 19, the arrangement being such as to cause the slider to move reciprocatively at each full turn of the hand wheel 23.

The cover 16 contains a round opening 27 and registerable therewith is a semilobular cavity 28 constituting a cup forme in the slider 26.

Journalled transversely in the slider, at the 95 axis of the cup are the trunnions of a scoop 29 adapted to scrape the interior of the cup, these trunnions having pinions 30 xed on their outer ends.

Engaging the pinicns are segments 31 fixed 160 on a pin 32 rotatably mounted in lugs` i353 e.\'- tending from the wall ot the cup 28 into the casing 1S) and fixed on the pin 32 is an arm C54 carrying a roll 35.

The scraper 2.() is normally held at the lower edge of the cup by a tension spring 36 which also retains the arm 84 substantially erect and in position to cause the roll to engage a plate cam 37 fixed to the interior ot' the casing 19 in such position as to oscillate the arm and cause the scraper to move over the interior surface of the cup, releasing its contents, as tbe slider is moved outwardly, to drop upon a receiver', as at 38, (see Fig. 3), in the form of a hemisphere 39.

In the modification shown in Figs. 5, G and 7, the drive shaft Q2 is replaced by another having sections 40 and 41, the hand- Wheel 23 being on the front section and the cam Q4 on the rear section.

The `forward end ot the rear section is enlarged as at 42 and provided with a socket receptive of the rear end of the shaft sec- .ion 40 to freely rotate therein and contains .'wo'opposedarcuate recesses 43 registerable with a single narrow recess 44 adapted to receive a coin 45 entered through a slot 46 in the top of the casing 19.

The recess 44 is normally held in register with the slot 46 by a tension spring 47, one end being fixed in the casing and the other to a collar 48 at the end of the cam 24, the collar having a pin 49 operable in a recess 50 in the side of the adjacent bracket 19, the pin acting as a stop, limiting the extent 'of rotation that can be imparted to the cam 24.

In operation the piston 15 having been pressed down to the bottom of the tank during the release of air from the pipe 14, the commodity to be dispensed is filled into the tank and the cover 16, with its attachment-s, secured thereover.

Thereupon compressed air being admitted through the pipe 14, the piston 15 is forced upwardly, pressingr the contents against the cover and through the opening Q7 into the inverted cup 28, at that time disposed directly over the opening.

Upon turning the hand-wheel the cam will rotate, causing the slider to advance, dis-` charge its contents and recede into a. receptive position.

The compressed air remains open to the piston and it will be apparent that equal amounts ot the material will be dispensed as rapidly as the shaft is rotated.

'l'be same etl'ects are. attained in the modified form ot apparatus except that it is arranged to receive a pre-payment coin and that the hand-wheel is given a halt turn only. returning to its initial position, at which time the coin 45 will drop into the space within the casing.

The toregoing disclosure is to be regarded as descriptive and illustrative. only, and not as restrictive or limitative ot the invention, of which obviously an en'ibodiment may be constructed including many modifications without departing trom the general scope herein indicated and denotedin the appended claims.

Having thusI described my invention. what l claim as new and desire to secure by Letters Patent` is:-

An apparatus tor dispensing plastic substances in equal quantities comprising a tank having a piston provided with pressure applyingr means. a cover removably engaged on said tank, said cover containing an opening. a casing on said cover, a slider having an inverted dispensing cup movable in said casing, and means in said casing to move the cup reciprocatively from over the cover opening to a point beyond said tank.
